摘要对采自摩洛哥Mugharet el 'Aliya更新世沉积物中的有蹄类动物牙釉质样品进行了电子自旋共振（ESR）测年。根据早期摄取（EU）模型和线性摄取（LU）模型，波浪引起的洞穴破裂和初始砂沉积（第10层）的年龄估计分别为62±6 ka bp和81±9 ka bp。来自第5层和第6层的Aterian职业和第9层的可能职业的样品产生了EU估计的年龄在39±4和44±5 ka bp之间，LU年龄在47±5和56±5 ka bp之间。除了整个欧盟和LU模型年龄范围外，Aterian职业的年龄在35和60 ka bp之间。当与已发表的，主要是放射性碳为基础的ca。40-20 ka bp的摩洛哥阿特里亚年表（例如，Debenath，1992），这些新的结果意味着Aterian到达或Mousterian到Aterian转变发生超过放射性碳方法的上限。
Abstract Electron spin resonance (ESR) dating has been carried out on ungulate tooth enamel samples from the Pleistocene deposits of Mugharet el ‘Aliya, Atlantic coastal Morocco. Age estimations for wave-induced breaching of the cavity and initial sand deposition (Layer 10) are 62±6 ka bp by the Early Uptake (EU) model and 81±9 ka bp by Linear Uptake (LU). Samples from Aterian occupations in Layers 5 and 6 and a possible occupation in Layer 9 yielded EU estimated ages between 39±4 and 44±5 ka bp and LU ages between 47±5 and 56±5 ka bp . Incorporating the entire range of EU and LU model ages, the Aterian occupations are dated to between 35 and 60 ka bp . When compared with the published, mostly radiocarbon-based ca. 40–20 ka bp chronology for the Moroccan Aterian (e.g., Debenath, 1992), these new results imply an Aterian arrival or Mousterian-to-Aterian transition occurring beyond the upper limit of the radiocarbon method.
